There is no way of telling whether they should have won or not. Ofc in hindsight every gambler can predict what move they "would have" made. But actually you cant. If the nounces where not skipped everything would have been different. Thus the only fair thing to do would be a complete rollback and all decisions would have to be made again without knowing the outcome.
Yes, there is. You can use a bet verifier and input the skipped nonce. You will see what you
would have got. The results are deterministic, as with every provably fair implementation.
